Rewrite A Query Efficiently
Mar 15, 2007
Is there a efficient way to write this query?
SELECT CASE
WHEN Population BETWEEN 0 AND 100 THEN '0-100' WHEN Population BETWEEN 101 AND 1000 THEN '101-1000' ELSE 'Greater than 1000' END AS Population_Range,
COUNT(CASE WHEN Population BETWEEN 0 AND 100 THEN '0-100' WHEN Population BETWEEN 101 AND 1000 THEN '101-1000' ELSE 'Greater than 1000' END) AS [No. Of Countries]
FROM Country
GROUP BY
CASE WHEN Population BETWEEN 0 AND 100 THEN '0-100' WHEN Population BETWEEN 101 AND 1000 THEN '101-1000' ELSE 'Greater than 1000' END

However, I'd like to enable a total for the day (340)
Thanks,

Hello,
I have a query with 11 left joins. Some hits against tables with small amounts of reference data, whereas others are not so small. Should I rewrite this in another way, as performance is a requirement on this one? Or, should I do it another way?
How would I rewrite left joins? Any examples?
Thanks.

Hello.
I have a query which spends a lot of time calculating my CASE WHEN -statements.
My query looks like this
SELECT TOP 250
UserId,
CASE WHEN
(someCol*0.4+someOtherCol*0.3) > 99 THEN 99
ELSE
(someCol*0.4+someOtherCol*0.3)
END
FROM
(
SELECT
UserId,
CASE WHEN @myparam > 50 THEN
CASE WHEN Col5+@myincrease > 99 THEN 99 ELSE Col5+@myincrease END
ELSE
CASE WHEN Col6+@myincrease > 99 THEN 99 ELSE Col6+@myincrease ENDEND as someCol,
CASE WHEN Col8+@myincrease3 > 99 THEN 99 ELSE Col8+@myincrease3 END as SomeOtherCol
FROM
SomeTable
) t1
This is just a little bit of the full query. I cannot write the whole query since it contains alot of different views and calculations, but I have traced it down to that all these case when-statements is taking a lot of time to do. So I hope that this example will be enough for you to understand my problem.
I know about some tricks that can replace a CASE WHEN, for example using COALESCE or BETWEEN but that does not seem to work in my case.
Any suggestions?

Is it possible to use wildcards with an equals statement? Such asSELECT * FROM Table WHERE City = '%' AND State='Ca'Bascially just stating where city equals anything...I know you can do it with a LIKE statement such as...SELECT * FROM Table WHERE City LIKE '%' AND State='Ca'but is that very efficient?The reason I want to do this is because I want to programmitcally set the city, so just ommiting it won't work
Also, using City LIKE '%' seems to not include NULL...is there anywayto include NULL as well as anything else?
Thanks for your help!

I hope I explain this correctly...
I'm required to allow users to order items in a field to be displayed on a page in the order they specified.
For example: A user can drag and drop items in a list to specify the order it will be displayed in.
I have my drag and drop code ready to do this.
I have an idea on how to do this but I think it’s too inefficient.
I was going to create an orderby field and populate it with a number that corresponds to the position of the item. However, as one can deduce, if a user drags and drops a record between two others, I would have to change not only its orderby number but then change all the other items orderby number.
For instances if I dropped an item with an orderby number of 3 between 6 and 7 I would have to change the 3 to a 7 and then recursively change all the other records orderby numbers up to 3 and then change everything after 7.
Well, I hope I make sense. It’s easier to visualize it on paper.
Does anyone know how to tackle this issue of user dynamic ordering?

My main table has the following structure:t1 (id_primary, id_secundary, name) i.e. [(1,1,"name1"), (2,1,"name2")]I want to join this table with the following second table:t2 (id_primary, id_secundary, value) i.e. [(1, NULL, "value1"),(NULL,1,"value2")]The join should first try to find a match on id_primary and only if thatfails it should find a match on id_secundary. Every row in t1 is matchedagainst a single row in t2.The following query works:selecta.name, isnull(b.value, c.value)fromt1 a left outer join t2 b on a.id_primary = b.id_primaryleft outer join t2 c on a.id_secundary = c.id_secundaryI'm wondering though if it would be possible to write a query that only usest2 once, since it actualy is quite a complex query that is calculated twicenow. Any ideas (besides using a temp table)?

I have an interesting problem:
I have an ASP.NET web application that uses a Treeview control to display what can potentially be a very large data set. In the past, I would just run a recursive stored procedure in my database that would output the XML which I would save to a file. The Treeview used the XML file as its data source. I did this because it can take so long for the stored procedure to run (10 seconds or more) that, it isn't practical to have the treeview point directly to the stored procedure. This worked well enough because the data didn't change very often.
Now, it looks as if the application will be used in a production environment, and I really need to find a way to supply up-to-date data to the treeview in a dynamic way. I have tried creating a view that would provide XML and that would be updated any time the target table is updated but, that has not worked. I have also tried creating a trigger that would output to an XML file any time an edit was made (using the xp_cmdshell functionality) but, that has proven difficult as well.
Is there a simpler solution that I am just missing? I just want an up-to-date XML representation of the data that is a result of a recursive function.
Thanks for any help you can provide.

We have a website that accesses our SQL databases. In the past, we used our internal employees to improve our SQL databases. However, we want to outsource the work.
There is a lot of information we would like to keep private from the outsourcing.
Is there a way to efficiently make test data throughout our database without changing our original database?
Is a way to easily update our database to the new changes?
I found this product through Google EMS Data Generator for SQL Server
http://www.sqlmanager.net/en/products/mssql/datagenerator
Would this program help us make test data?
Thanks in advance

I have a WHERE clause that could be an "=" or a "LIKE" depending uponif the passed variable is populated or not. I would like to know thebest way to write the WHERE clause to make it dynamically switchbetween the 2 and make best use of the indexes.CREATE TABLE myTable(ID INT PRIMARY KEY CLUSTERED, COUNTY VARCHAR(50))CREATE INDEX IDX_myTable_County ON myTable(COUNTY)DECLARE @COUNTY VARCHAR(50)SET @COUNTY = 'SANTA CLARA' -- Could also be SET @COUNTY = NULLSELECT ID FROM myTableWHERE COUNTY LIKE (CASE WHEN @COUNTY IS NOT NULL THEN @COUNTY ELSE '%'END)This does not seem like best practice to me because I am forced to use"LIKE" even when @COUNTY is populated with data. Ultimately I'd like:WHERE (CASE WHEN @COUNTY IS NOT NULL COUNTY = @COUNTY ELSE COUNTY LIKE'%' END)but that is incorrect syntax on "=".Also, I do not want to use a dynamically built statement. Is there away around this?Thanks,Josh

Currently I just need to rechange a view which is writen by other staff member because of low performance.
This view comprises 4 query statement and link using Union statement.
Each query statement will refer more than 8 tables and other views.
Now I want to rewrite it but I can not know how to do. I change union to CTE, no performance improved.
I want to create indexed view, but because this view refer the other view, I cannot create index on it?
Any tips for me? Thank you for help.

Hi,I'd be interested in people's thoughts about the following. A user on my site will be searching for a venue name, and that could officially include a sponsor which the user might not search for. Now I am using the AutoCompleteDropdown from the AJAX Control Toolkit, so the user will start typing in a few characters and the results will be returned. I can generate the results from sql by doing a simple LIKE '%' + @searchTerm + '%' however, this fills me with great fear of table scans. At the moment, we'd be querying against a table of 5K records, but our application is very new.I'm thinking one option is to split the words into another table - a one to many relationship to hold each word of the venue. The benefit of this would be that you could do a:LIKE @term + '%'but then I have the cost of the join. (And the added complexity which is not a major issue)Any thoughts/tips?Thanks!

We have a SQL Server 2012 Enterprise live transactional database that is now growing over 1G per month and is becoming a size problem for us. It is currently at 23G. Character type fields are all Unicode and I have calculated a savings of 5G in space converting only 2 such fields averaging 206 characters each to non-Unicode, and almost 10G in space if we convert a few more of them from nchar and nvarchar to char and varchar types. These fields will never have a requirement to hold Unicode characters that cannot be in the SQL_Latin1_General_CP1_CI_AS collation as they come in as plain ASCII originally and will always do so per the protocol standard.
I’m the software architect and chief C# developer though only a DBA hack or I would not have designed our database to have Unicode fields for high volume tables that did not need Unicode for those fields when the database was created 3 years ago. I want to correct this mistake now before we finalize converting to an AlwaysOn environment to support with various performance and backup issues.
After downsizing these two or more fields, we would like to shrink the database one time to take advantage of the space savings for full backups, and for seeding an AlwaysOn environment.
1.What is the safest and most efficient conversion technique for downsizing columns from nchar/nvarchar to char/varchar types? Esp. when there are multiple fields in the same table to be converted. I tested doing an “add new column, set new=old, drop old, rename old to new” for both of the main two fields I want to convert from nvarchar(max) to varchar(max), and it took 81 minutes on our test server (4 virtual core, 8G memory) before running out of disk space even though there was 8G left on the disk, and the db has unlimited size set (Could not allocate space for object 'dbo.abc'.'PK_xyz' in database 'xxx' because the 'PRIMARY' filegroup is full). I did delete an old database before it finished after getting a disk warning so maybe it did not count that new space. Regardless it was too slow. And this was on just the two largest of these columns (12.6M rows) and only ran 2 to 3% CPU busy so seemed not very efficient, and indicated unacceptable downtime if we were to convert even these two fields much less any additional fields. Average field size for these two fields was only 206 characters or 412 bytes each. Another technique I plan to try is to create the new table def in a new schema, select into it from the old table, then move tables amongst schema and delete the old table. I have a FK and indexes to contend with on the table.
2.If I figure out how to do #1 efficiently within an acceptable maint window, what is the safest practice for doing a one-time shrink and end up with organized/rebuilt indexes and updated Statistics? I understand the logic of not doing regular shrinks and that sometimes it can actually increase the size.
3.Is there any third party tool that could take a backup and restore it into a new database with the modified field definitions or otherwise convert certain field types?

Situation:
SQL Server 2000.
At my new employer they have a production database on one server and a copy of it that is set to read only on another server which is used for reporting.
#1
They have an SQL Server Agent job on the production server that: (2 times a day)
Backs up the production database
Copies the backup file to a directory on the reporting server. (Its pretty big and can take time if there are problems with the LAN)
#2
They have an SQL Server Agent job on the Reporting server that: (scheduled to run 2 hours or so after the job on server 1 has runthey figured that it would be a safe bet that the backup and copy process of the first job would be done by then)
Breaks the user connections to the reporting database
Performs a restore on the reporting database using the backup file that was copied to the holding directory by the production job.
Sets some permissions for various users.
Sets the reporting database to READ ONLY.
What I would like to do is find a more efficient way to create this reporting database, I have started doing research into DTS methods but would like some opinions from more experienced users.
Thank You,
Wade

Hello all
We are load testing SQL 2005 and I need to re-write the index scripts that we have from 2000. Is there an easier way to rewrite the scripts without having to go to each job, then each step and modify it?
Our current index script template is:
Create NonClustered Index [IdxABCDE]
On dbo.blahblah(blahID)
With FillFactor = 90, Statistics_NoRecompute
On [Index2]
Go
and I need to rewrite it as:
ALTER INDEX [IdxABCDE] ON [dbo].[blahblah]
REBUILD WITH (FILLFACTOR = 90, ONLINE = OFF,SORT_IN_TEMPDB=ON, STATISTICS_NORECOMPUTE = ON, MAXDOP=4)
I am thinking I would have to rewrite the scripts from scratch. We have hundreds of index scripts. So before I brace myself to lot of typing, just wanted to find out if there is any easier way..
Thanks..

INNER JOIN @BlogView BC ON BC.CommonID = BE.BlogCommonID
INNER JOIN vw_Blog B ON B.BlogID = BC.BlogID

This works, but it's highly unefficient and generates a lot of IO. Is there another way to do it without the use of temp tables?
Code Block
select eh.*
from Equipment_History eh
where Equipment_History_ID in
(select top 2 Equipment_History_ID
from Equipment_History eh1
where Equipment_ID in
(select Equipment_ID
from Equipment_History eh2
where Equipment_History_ID in
(select min(Equipment_History_ID)
from Equipment_History eh3
where eh2.Equipment_ID = eh3.Equipment_ID
and eh2.Equipment_Status_Type in (1,2,3)))
and eh1.Equipment_ID = eh.Equipment_ID
order by Equipment_History_ID)
Equipment_History_ID is PK
Let me know what other information would be useful, I can barely understand my logic from looking at the code but it does in fact work.

Hello,
I need to sample data in a very large table in SQL Server 2000 (a gazillion rows of Performance Monitor statitics).
I'd like to take the top 5%, for instance, based upon a column containing random numbers.
Can anyone suggest a highly efficient method of populating a column with random numbers.
Thanks in advance.

I have to modify a stored procedure that is written by someone else.Basically the stored prcoedure uses a cursor to fetch the data from the table and then insert that data in another table. While fetching the code form another table, it also gets some distinct columns from another table Below is my code:
Declare data_cursor cursor for
Select emp_no, emp_name, event_date, Test_no, Code, Test_result
From test_table1
order by emp_no
[code]...
The reason, I have to modify the above stored proc because now because of application changes, I am getting around 50 distinct userID from test_table1 so the above subquery(SELECT @ProcessName = (select distinct userID from test_table1) won't work. How can I loop through the above stored proc so that each @ProcessName can get inserted in table TESTTable2 so in other words
I want to pass each userId one at a time and insert it in table test_table1 and other subsequent tables. I can declare another cursor to accomplish this, but I was wondering if there is any better way to rewrite this stored proc and not use the cursor at all.because of my application changes all these three statements above are throwing the error:
SELECT @ProcessName = (select distinct userID from test_table1)
SELECT @FileProcess = 'EW' + @ProcessName
Select @TestProcess = (Select distinct userID from testTable1) + 'TXT'

Community:
Suposse that some models are deployed in Report Server for a while, and users have developed some ad-hoc reports on them using Report Builder, (some of the models are SSAS Cubes).
Modifications are required for a Model, what is the procedure to deploy this modifications? What happens with ad-hoc reports of this Model? Rewrite all the reports is a VERY BAD option, I agree that some reports must be rewrote, but only if they reference objects no longer valids in new model.
I suposse that the procedure for SSAS Cube Models will be different for a Relational Database Source because metods of generating models are so different. (I am particularly curious about Cubes, I can't figure out how I can do it)
Suggestions and links will be very appreciate.
Regards

ok can someone tell me why i get two different answers for the same query. (looking for last day of month for a given date)
SELECT DATEADD(ms, - 3, DATEADD(mm, DATEDIFF(m, 0, CAST('12/20/2006' AS datetime)) + 1, 0)) AS Expr1
FROM testsupplierSCNCR
I am getting the result of 01/01/2007

SQL Server 2005 9.0.3161 on Win 2k3 R2
I receive the following error:
"Error: 8624, Severity: 16, State: 1 Internal Query Processor Error: The query processor could not produce a query plan. For more information, contact Customer Support Services."
I have traced this to an insert statement that executes as part of a stored procedure.
INSERT INTO ledger (journal__id, account__id,account_recv_info__id,amount)
VALUES (@journal_id, @acct_id, @acct_recv_id, @amount)
There is also an auto-increment column called id. There are FK contraints on all of the columns ending in "__id". I have found that if I remove the contraint on account__id the procedure will execute without error. None of the other constraints seem to make a difference. Of course I don't want to remove this key because it is important to the database integrity and should not be causing problems, but apparently it confuses the optimizer.
Also, the strange thing is that I can get the procedure to execute without error when I run it directly through management studio, but I receive the error when executing from .NET code or anything using ODBC (Access).

Hey, i've written a query to search a database dependant on variables chosen by user etc etc. Opened up a new sqldatasource, entered the query shown below and went on to the test query page. Entered some test variables, everything works as it should do. Try to get it to show in a datagrid on a webpage - nothing. No data shows.
SELECT dbo.DERIVATIVES.DERIVATIVE_ID, count(*) AS Matches
FROM dbo.MAKES INNER JOIN
dbo.MODELS ON dbo.MAKES.MAKE_ID = dbo.MODELS.MAKE_ID INNER JOIN
dbo.DERIVATIVES ON dbo.MODELS.MODEL_ID = dbo.DERIVATIVES.MODEL_ID INNER JOIN
dbo.[VALUES] ON dbo.DERIVATIVES.DERIVATIVE_ID = dbo.[VALUES].DERIVATIVE_ID INNER JOIN
dbo.ATTRIBUTES ON dbo.[VALUES].ATTRIBUTE_ID = dbo.ATTRIBUTES.ATTRIBUTE_ID
WHERE ((ATTRIBUTES.ATTRIBUTE_ID = @ATT_ID1 and (@VAL1 is null or VALUE = @VAL1)) or
(ATTRIBUTES.ATTRIBUTE_ID = @ATT_ID2 and (@VAL2 is null or VALUE = @VAL2)) or
(ATTRIBUTES.ATTRIBUTE_ID = @ATT_ID3 and (@VAL3 is null or VALUE = @VAL3)) or
(ATTRIBUTES.ATTRIBUTE_ID = @ATT_ID4 and (@VAL4 is null or VALUE = @VAL4)) )
GROUP BY dbo.DERIVATIVES.DERIVATIVE_ID
HAVING count(*) >= CASE WHEN @VAL1 IS NOT NULL THEN 1 ELSE 0 END +
CASE WHEN @VAL2 IS NOT NULL THEN 1 ELSE 0 END +

AFAIK I have configured the source to pick up the dropdownlist value and the textbox value (the text box is autopostback).
Am i not submitting the data correctly? (It worked with a simple query...just not with this one). I have tried a stored procedure which works when testing just not when its live on a webpage.
Please help!
(Visual Web Devleoper 2005 Express and SQL Server Management Studio Express)

I have the following code.
SELECT _bvSerialMasterFull.SerialNumber, _bvSerialMasterFull.SNStockLink, _bvSerialMasterFull.SNDateLMove, _bvSerialMasterFull.CurrentLoc,
_bvSerialMasterFull.CurrentAccLink, _bvSerialMasterFull.StockCode, _bvSerialMasterFull.CurrentAccount, _bvSerialMasterFull.CurrentLocationDesc,
_bvSerialNumbersFull.SNTxDate, _bvSerialNumbersFull.SNTxReference, _bvSerialNumbersFull.SNTrCodeID, _bvSerialNumbersFull.SNTransType,
_bvSerialNumbersFull.SNWarehouseID, _bvSerialNumbersFull.TransAccount, _bvSerialNumbersFull.TransTypeDesc,
[code]...
However, as you can see, the original select query is run twice and joined together.What I was hoping for is this to be done in the original query without the need to duplicate the original query.

I'm trying to find the command to open up an odbc conection inside sql2005 express. I only have ues of an odbc connector, we're conection to remedy. We will eventually be using stored procedures to extract the data we need from remedy and doing additional data crunching. I'm a foxpro programmer so once I get the correct syntax for making the odbc connector I shold be ok. Also I need a really good advanced book on sql2005. The type of book that would have my odbc answer. I've spent all morning trying to find this information and was unable to.
Thanks in advance
Daniel Buchanan.
If this was the wrong forum to post this on, please move this question to the correct one. I need this answer soon.

insert into #temptable

-- The 3rd query uses an incorrect column name in a sub-query and succeeds but rows are incorrectly qualified. This is very DANGEROUS!!!
-- The issue exists is in 2008 R2, 2012 and 2014 and is "By Design"
set nocount on
go
if object_id('tempdb.dbo.#t1') IS NOT NULL drop table #t1
if object_id('tempdb.dbo
[code]....
This succeeds when the invalid column name is a valid column name in the outer query. So in this situation the sub-query would fail when run by itself but succeed with an incorrectly applied filter when run as a sub-query. The danger here is that if a SQL Server user runs DML in a production database with such a sub-query which then the results are likely not the expected results with potentially unintended actions applied against the data. how many SQL Server users have had incorrectly applied DML or incorrect query results and don't even know it....?
